The paper questions the methodology of "economics and psychology". It focuses on the case of hyperbolic discounting. Using some experimental results, I argue that the same sort of evidence which rejects the standard constant discount utility functions can just as easily reject hyperbolic...

The Kydland-Prescott, Barro-Gordon inflation bias result relies on the presumption that policymakers aim at achieving a level of employment above the normal level. This presumption has been recently questioned by both academics and policymakers on the ground of realism. This note shows that even...

A consumer has to make a consumption decision. She is modeled as making a binary decision regarding a suggested change to her status quo. An affective package refers to the totality of affective responses that the consumer is expected to have to the various aspects of this decision. It is...

We study environments where a production process is jointly shared by a finite group of agents. The social decision involves the determination of input contribution and output distribution. We define a competitive solution when there is decreasing returns-to-scale and show that it leads to a...

A decision maker faces a decision problem, or a game against nature. For each probability distribution over the state of the world (nature`s strategies), she has a weak order over her acts (pure strategies). We formulate conditions on these weak orders guaranteeing that they can be jointly...

This note provides an axiomatic derivation of a case-based decision rule. It shows that, if preferences orders over available acts in various contexts satisfy certain consistency requirements, then these orders can be numerically represented by maximizationof a similarity-weighted utility function.
